Electrical connection
The power connection of EnCal3000 Quad is made in each unit by a 3-pin connector on the interconnection
board.
The processor board is only available in the master unit, therefore for the data transfer from channel 3 and 4,
between the Master and the Slave Unit exists. The Power Supply becomes connected in each housing
separately.
With the help of connections the interconnection boards are connected 1 to 1 in the two housings and
transfer the data. These wire connections should not be changed by the customer.
There are no customer connections for data transfer in the Slave Unit, these are all made in the Master Unit.
The following figure shows the location of the plug connection for data transfer (black plug) on the
Interconnection boards and in the device. Above the connection on the Interconnection Board is visible, the
lower part of the figure shows the position of connection in the real device.
